Data just disappeared I still don't have it

I was at the Santon branch on 11 July 2015 to do my upgrade. Leo gang assisted me and I am happy with her service but my issue is that when my package was upgraded my data that I had (700 MB) just dissapeard. Leo gang said that I should get it back by 13 July 2015 and logged a request for it. It's Neen almost 2 weeks and I still don't have my data back? To top it all off on the 21st July when I had my minuites credited I was also supposed to get 300 MB of data and 200 sms which did not come through. To me this is a display of incompetency. I logged the query with lebogang in the Santon branch but was told that it could take up to 7 days. I will not accept this kind of incompetency twice in a period of 2 weeks. I need my data credited very soon.
